A depressed middle age man Happa comes to a remote cabin carrying a 3 feet firework ball. He has a plan to commit a suicide together with members of an inter-net suicide chatroom called “Life Club.” The other members come one by one but they are shocked to meet the last one, a high school girl Tsukiko and they try to convince her not to kill herself. Being treated as a child too young for no reason to die, she gets mad at the other members and pushes the button to ignite the firework. But after a while, Happa realizes that he is in the same room on the same day. Every time they try but fail to save Tsukiko, they return to the start. Why they are stuck in a time loop? Is the future waiting ahead of them despair or hope?
